Company History and Business Evolution

Founded in 1987 by Andrew Florance, CoStar Group, Inc. began as a small startup with a mission to digitize and centralize commercial real estate data. At a time when property information was scattered across printed directories and handwritten notes, Florance envisioned a platform that would bring transparency and efficiency to a fragmented market. The early years were marked by painstaking data collection—employees manually gathered details on office, retail, and industrial properties across major U.S. cities. By 1998, CoStar had established itself as the definitive source for commercial real estate information, and the company went public on the Nasdaq under the symbol CSGP. The early 2000s saw a series of strategic acquisitions that expanded CoStar's capabilities: the purchase of Property & Portfolio Research (PPR) added advanced analytics; the acquisition of LoopNet in 2012 created the largest online marketplace for commercial real estate; and the purchase of Apartments.com in 2014 propelled the company into the multifamily rental space. Subsequent acquisitions of BizBuySell (2018), LandsofAmerica (2019), and Ten-X (2020) further diversified the product portfolio. Throughout its evolution, CoStar Group, Inc. has invested heavily in technology, employing machine learning, artificial intelligence, and automated data validation to maintain its competitive edge. The company's ability to adapt to changing market dynamics—such as the rise of remote work and the need for real-time data—has ensured its continued growth. Today, CoStar Group, Inc. operates in over 30 countries, with a data repository covering more than 5 million properties and millions of lease records. Its evolution from a niche data provider to a comprehensive real estate ecosystem exemplifies visionary leadership and relentless execution.
